ADHD Focus Simulator – Distractions, Time Warp and Overload Test
Experience ADHD-style distractions, time warp and overload. A free online simulator to feel and measure real-world focus challenges.
ADHD Focus Simulator is an interactive web tool that lets you actually feel what ADHD-style focus challenges are like — and also measure how you react to them. Instead of just reading about ADHD, users step into a live, distraction-filled environment and see how their focus, timing and stress levels change in real time.
The simulator runs as a guided session. First, you choose a mode or run all of them in sequence. In Distraction Bombardment Mode, you’re given a simple task such as reading a short paragraph or tracking a moving dot. While you try to focus, random pop-ups, notification bubbles, fake chat messages, highlight flashes and tiny sounds start appearing on the screen. The tool logs every time you click away, pause, or lose the task, then calculates a “Distraction Resistance Score”.
Next is Focus Training Mode. Here, the goal is to stay locked on a central task while ignoring decoy elements. You might have to click specific shapes, type a code, or follow an arrow sequence while distractions float around the screen. This mode gives you a Focus Streak, Reaction Speed and Missed Task count, turning focus practice into a small game that can be replayed and improved over time.
Then comes Time Warp Mode, which simulates ADHD-style time blindness. A visible timer speeds up, slows down or jumps while you estimate when, say, 30 seconds have passed or a deadline “feels” close. At the end, the tool shows how early or late your guesses were and how your internal sense of time was distorted by on-screen distractions.
Finally, Overload Mode throws multiple mini tasks at you at once: sorting items, clicking reminders, reacting to color changes, or dismissing alerts. Your overload meter rises as you miss tasks or let items pile up. This mode is designed to demonstrate how quickly the brain can become overwhelmed when too many inputs arrive at the same time.
At the end of a session, ADHD Focus Simulator generates a simple report: Distraction Score, Focus Score, Time Perception Error, and Overload Index. This makes the tool useful for teachers, therapists, parents, and friends who want to understand ADHD challenges in a safe, digital sandbox. It’s not a medical test or diagnosis, but a powerful awareness and education tool that visualizes what words can’t fully explain.
